Growing Tips

  • 1Plant Swiss chard in a spot that gets full sun to partial shade, ensuring it receives at least 4-6 hours of sunlight daily.
  • 2Keep the soil consistently moist but not waterlogged, watering deeply once or twice a week.
  • 3Use well-draining, nutrient-rich soil, and space plants about 12-18 inches apart to allow for good air circulation and growth.
  • 4To manage pests, regularly inspect leaves for signs of damage and use organic methods like neem oil or insecticidal soap if needed.

How to Harvest

  • 1Harvest Swiss chard when the leaves are about 6 to 8 inches long and firm.

  • 3Avoid pulling the leaves to prevent damaging the plant.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from your Swiss Chard plant is easy and rewarding! Simply let a few healthy plants grow through the season until they send up tall flower stalks and produce seeds, which look like small, round clusters. Once the stalks turn brown and dry, gently cut them and shake the seeds into a paper bag. Let the seeds dry for a week in a cool, dry place, then store them in a labeled envelope or jar in a dark, dry spot—your seeds will be ready for next season! With just a little patience, you’ll have your own homegrown Swiss Chard seeds and the satisfaction of starting your next crop from scratch.
